Product Information

Full details

The Rubbertech PEDECK CRADLE1250 is an essential solution for decking contractors and DIY enthusiasts looking to create level, raised timber or composite decks on uneven surfaces like balconies, roof terraces, and patios. These durable supports offer a precise 12mm to 50mm height adjustment, effectively lifting joists off the substrate to prevent moisture buildup and rot. While the 60-pack is ideal for larger installations, users should note that they are specifically designed for joist-based support systems and are not intended for direct board attachment without a frame.

FAQs

Can these be used on roof terraces?

Yes, the rubber base is designed to protect delicate roof membranes and provide the necessary grip for elevated decking.

What is the maximum load capacity?

Each cradle features a compression resistance of 16kN, making it suitable for both residential and commercial applications.

Are these suitable for composite joists?

Yes, they are compatible with both timber and composite joist systems, provided the joists are secured through the cradle's fixing points.

Can I use these for heights over 50mm?

No, the range is strictly 12mm to 50mm. For higher elevations, you would need a different stacking support system.

Do I need special tools to adjust them?

No, they are designed for manual height adjustment using the threaded head, requiring no specialized tools.

How many cradles are in a pack?

This product comes in a pack of 60 units.

Troubleshooting

Cradle is unstable on uneven ground

Ensure the rubber base is placed on a flat, debris-free surface. If the substrate is crumbling, use a solid paving slab or support plate underneath.

Joists are not perfectly level

Check the thread adjustment on each cradle. If a cradle reaches its maximum 50mm height and is still too low, consider using a wider sub-frame or re-leveling the substrate.

Difficulty rotating the adjustment head

Ensure there is no grit or debris caught in the thread. Clean the threads with a brush if rotation becomes stiff.

Pros and Cons

Pros

  • Wide 12mm to 50mm height range accommodates most uneven substrates
  • High 16kN load capacity ensures structural stability
  • Rubber base promotes drainage and prevents moisture-related decay
  • Easy-to-use screw-thread adjustment allows for quick leveling
  • Compatible with both timber and composite joist systems

Cons

  • Requires professional-grade joists to function properly
  • Not suitable for direct ground installation without proper prep work
  • Larger pack size may be excessive for very small patio projects

Setup, Compatibility & Care

To set up your deck, first ensure your substrate is clean and stable. Lay out your joist grid and place the CRADLE1250 units at the required intervals. Adjust the height of each cradle by rotating the threaded head until the joist is perfectly level, using a spirit level as you progress. Once the height is set, drive appropriate screws through the cradle’s fixing points directly into your timber or composite joists. These cradles are low-maintenance; however, it is recommended to periodically clear away any organic debris or standing water from the drainage paths beneath the joists to ensure the long-term effectiveness of the rubber base pads.
